cfinder III
infrared laser range finder - range from 0.3m up to 150m
Your tool for keeping in focus
cfinder III is the smallest, lightest and most advanced laser range finder ever developed by cmotion. Using a certified class 1 laser, cfinder III can accurately measure up to 10x faster than regular ultrasonic devices and measure distances up to 150 m.
cfinder III can be used directly with any cvolution or ARRI system as well as a range of other systems supporting ARRI‘s UDM protocol. When used in combination with cmotion lens data or ARRI LDS, cfinder III can provide a sophisticated auto-focus solution.
The in-built multi-function display not only displays a high resolution distance read-out but also a clear navigation through the cfinder III‘s menu. As with previous generations of cfinder, a reflector sight can be mounted to allow the operator to track a moving subject independent from the camera.

FAQ`s
Is the cfinder III eyesafe?
Yes, both, the measuring laser and the adjustment laser are certified as eye safe. However staring into any visible class 2 laser may cause permanent eye damage.
Is there a divergence of the measuring beam?
The infrared laser does have a slight divergence. At a distance of 50 meter the divergence is 141 x 24 mm.
How do I mount the cfinder III?
The cfinder III does offer an ARRI mounting cube with 3/8” UNC-16 bushing. We do reccommend standard fastening tools like a Noga arm or ULCS mounting accessories.
